Abstract
A dressing of calcium alginate for quick absorption and haemostasis is made up of non-woven cloth of calcium alginate through needling one surface of said non-woven cloth, coating adhesive on it, sticking protecting paper and coating detackifier on other surface, and features quick shaping, high productivity and use effect, easy application, good air permeability and no adhesion to wound.
Description
The present invention relates to the making of medical dressing, be mainly used in fast Absorption, hemostasis and adhesion wound surface, belong to medical dressing and make the field.
Background technology of the present invention: publication number CN1068158A, title " facture of absorbable hemostatic dressing ".This characteristic feature of an invention is: with 20～200CPS, the aqueous solution of the dirty sour sodium of algae of best 95～105CPS is as spinning solution, and solutions employed is water, preferably deionized water; The dirty sour sodium solid content of algae that is made into stock solution is 3～10 (weight) %, and preferably 4.5～5.5 (weight) % adopts calcium chloride as coagulant, contains calcium chloride 1～6 (weight) %, the aqueous solvent of best 1～2 (weight) %, and setting time is 10～50 seconds; Jet stretch is controlled to be 10～30% in the wet spinning process, is preferably 18～22%; Adopt the dirty silicate fiber of dry state algae to make non-woven fabrics by combing, lapping, needling process, the length of the dirty silicate fiber of algae is chosen as 55～65mm.It is not enough point: the sampling of the sampling of specifications of raw materials, the proportioning of solution concentration and coagulant concentration, making its nascent tow is 10～50 seconds satisfying setting time, can only derive with the speed of 6 meters/minute or 10 meters/minute.Therefore the spun filament molding is slow, and production efficiency is low, cost is high, the incompatibility industrialized mass production.
The purpose of design that Hair Fixer is bright: avoid the deficiencies in the prior art part, by to the selection of specifications of raw materials, the proportioning of solution concentration, coagulant concentration allotment, making its nascent tow is under 0.001～1 second the condition, to derive with 40 meters/minute speed in setting time.
Design of the present invention: the present invention is on the basis of existing background technology, realizes by selection, weaving solution concentration and coagulant concentration allotment to its specifications of raw materials.Its organization plan: Application containing calcium alginate, the one side of the netted calcium alginate non-woven fabrics of acupuncture (4) adopts adhesive (3) to be bonded in the one side of non-woven fabrics (2), the another side of non-woven fabrics (2) scribbles antitack agent (1), protective paper (5) is positioned on the another side of the netted shape calcium alginate of acupuncture non-woven fabrics, around it be positioned at adhesive (3) stick on the non-woven fabrics (2) and peelable.The manufacture method of calcium alginate fibre non-woven fabrics, with the 250CPS sodium alginate is raw material, with the distilled water is solvent, being made into weaving liquid concentration is 2.8% or 4% or 11%, calcium chloride water with 10% or 16% or 20% concentration is a solidification liquid, weaving liquid grinds through colloid mill, three road sheet frame pressure filter filter pressings, quantitatively back and the spinning head that is pressed through the 0.08mm aperture directly are pressed into and solidify in the liquid pool by dosing pump, the dark 30cm of its coagulating bath, draft speed is that 40m/ divides and uninterruptedly is distracted into fiber in the bath, through cleaning, drawing-off, centrifuge dehydration, alcohol is handled, dry, cut off, length is 10cm, again through combing, cross lapping, acupuncture, be processed into non-woven fabrics.Draw ratio is 1: 1.2.
The present invention compares with background technology, adopting the 250CPS sodium alginate is raw material, the concentration that is made into the distilled water solvent is 2.8% or 4% or 11% spinning liquid, with concentration is that 20% calcium chloride water is a coagulant, making the present invention have one is the advantage that the spun filament molding is fast, production efficiency is high, clinical result of use is good, the 2nd, the Application containing calcium alginate that this calcium alginate non-woven fabrics is made, have easy to use, stick comfortable, good permeability, the wound healing piece, and the adhesion wound surface, the 3rd, molding is fast, production efficiency is high, clinical effectiveness is good.
Description of drawings:
Fig. 1 is the structural representation of Application containing calcium alginate.
Fig. 2 is that structural representation cuts open in the office of Application containing calcium alginate.
Embodiment 1: the fine paper non-woven fabrics of calcium alginate is to be raw material with the sodium alginate, and raw material specification is 250CPS, with the distilled water be solvent to be made into concentration of dope be 4.0%, be solidification liquid with the calcium chloride water of 20% concentration.Spinning liquid grinds through colloid mill, three road sheet frame pressure filter filter pressings, and the spinning head that quantitatively is pressed through the 0.08mm aperture by dosing pump directly is pressed into solidification liquid, the dark 30cm of coagulating bath, draft speed is the 40m/ branch in the bath, and through cleaning, drawing-off, draw ratio is 1: 1.2 to above-mentioned fiber again.Centrifuge dehydration, alcohol processings, drying, cut-out, length are 10cm, directly combing again, non-woven fabrics is processed in cross lapping, acupuncture, cuts into certain specification again and ventilative non-woven rubberized fabric is compound.It is back lining materials that ventilative non-woven rubberized fabric adopts the non-woven fabrics of Tianjin papermaking institute production, one side is coated with adhesive (outsourcing), another side is coated with acrylate viscose glue (Beijing Rhom and Hass produces), makes the ventilative adhesive plaster of nonwoven, pastes usefulness again for producing calcium alginate.
Embodiment 2: the structure of Application containing calcium alginate is: the one side of the netted calcium alginate non-woven fabrics of acupuncture (4) adopts " acrylic acid " adhesive (3) to be bonded in the one side of non-woven fabrics (2), the another side of non-woven fabrics (2) scribbles antitack agent (1), protective paper (5) is positioned on the another side of the netted shape calcium alginate of acupuncture non-woven fabrics, around it be positioned at " acrylic acid " adhesive (3) stick on the non-woven fabrics (2) and peelable.
